    This thread is for those that want to compare Joycon (L)'s and see if there is a trend in which are affected with issues where the left joycon desyncs or makes Link run off the edge of a cliff (general Nintendo problem/solution cases here). I got curious after reading this CNET article.

    There are 4 tri-wing screws that need to be removed from the back in order to access the date-of-manufacture dials and battery product number. Tri-wing screwdrivers are pretty cheap, and the screws have been used on parts of almost every console for years (GBA, GC, Wii, WiiU, Switch, etc), so it's not bad to keep in the toolbox. :)

    From there, there's a little adhesive on the battery tray (under the battery), but I was able to pull the battery up by going slow and gradually applying more force with a flathead screwdriver. There are 3 phillips screws to remove to see the circuit board: two under the battery (top-left and bottom-right screws, the other 2 hold the circuit board down and can be skipped) and one at the bottom left of the controller.

    Maybe if enough people want to contribute, we can start a spreadsheet.

    I have 2 Joycon-L's, and I'm guessing they were made in different factories by the differences that are in the dials alone. It's odd to me that there are varying battery product numbers though. I have pictures of most things if anyone wants them.

    Any ideas on the bottom dials, or any other numbers that I don't currently have labeled?

    Wouldnt it be far easier to sort by serial number so we can narrow it down from batches within those numbers?

    Bottom left and right seem to indicate day, each being the individual digit that combine to give 06, as in 12/06/16

    Where are the serial numbers for the Joycons? I only see a serial number on the battery itself.
